Abstract
A method of generating values of a predistortion look up table for linearization of a transmitter. The method includes accumulating a plurality of pairs of values representing input and output values of samples entering one or more non-linear elements of the transmitter, fitting the pairs of values into a parameteric model of at least one of the one or more non-linear elements, so as to determine values for the parameters of the parameteric model, and generating values of the look up table responsive to the fitted parameteric model.
